Best mmWave Presence Sensors for Home Assistant 2026

The SONOFF SNZB-06P24 Zigbee Presence Sensor (24GHz) earns the top open-stack composite of 8.9 on the SHE Local Control Score. Its normalized no-cloud factor scores 100%, because it pairs over ZHA or Zigbee2MQTT with zero cloud touchpoint. Its protocol-openness factor reaches 88%. What that composite delivers for your configuration is concrete. The radar reports presence directly to your coordinator. The self-learning calibration dials in the room automatically. CNET rates this 24GHz band the modern mid-band sweet spot, and at $24.90 it undercuts every 60GHz pick in the field.

The sensor yields configurable timeout and sensitivity clusters inside HA, and Tom's Guide notes this cluster access separates an open Zigbee sensor from a vendor-locked one because it exposes occupancy timeout and sensitivity as editable Z2M settings rather than burying them in closed firmware. Because its 24GHz zone positioning suppresses out-of-zone movement, a corner ceiling fan produces fewer ghost triggers than the cheaper 5.8GHz band delivers across a comparable room, which is why this guide weights that resilience heavily within the composite.

Compared to the THIRDREALITY Smart Presence Sensor R3 (60GHz Zigbee) at $49.99, the SNZB-06P24 costs roughly 50% less at $24.90. It gives up breathing-level precision for a price that enables whole-house deployment in this roundup.

The THIRDREALITY Smart Presence Sensor R3 (60GHz Zigbee) earns a composite of 9.1, the highest mains-powered Zigbee mark in this roundup. For your HA setup that delivers 60GHz precision without a cloud compromise. Its normalized no-cloud factor maxes out, since it pairs natively over ZHA or Zigbee2MQTT and exposes configurable clusters. The 60GHz band detects micro-movements as small as breathing, so it holds a room occupied where a coarser radar drops out. CNET frames 60GHz as the tightest still-presence band available to consumers.

The R3 also yields a working Zigbee repeater, which strengthens mesh resilience for downstream battery devices. The Verge notes that 60GHz airflow rejection beats the mid-band radars, so a running fan produces fewer false triggers. USB-C power keeps the install tidy, and the RGB status light confirms pairing state without opening HA.

Compared to the Aqara Presence Sensor FP2, the R3 matches much of the 60GHz detection quality. It does so on an open Zigbee path rather than the Aqara unit's Wi-Fi and HomeKit Controller route.

The AKAMATIS Human Presence Sensor v2.2 (ESPHome / LD2410B) earns the top composite of 9.4 on the SHE Local Control Score. Its no-cloud and protocol-openness factors both max out, because the firmware is flashable ESPHome that runs entirely on your LAN. For your HA setup that delivers the most tunable surface in the field. The Verge notes that community LD2410 builds report near-zero polling latency, and one test clocked an ESPHome unit 10 seconds faster than a motion-detection camera. Every gate, threshold, and reporting interval is configurable in YAML.

The LD2410B yields total control, which is precisely what the openness factor rewards. CNET frames flashable ESPHome firmware as the openness ceiling, ahead of any native Zigbee cluster access. The catch is false-trigger resistance, the lowest sub-score here, since the raw radar is airflow sensitive until you manually dial in the per-gate distance thresholds.

Compared to the SONOFF SNZB-06P24 Zigbee Presence Sensor (24GHz), the AKAMATIS trades plug-and-play calibration for total tunability. That produces a better outcome for a tinkerer and a worse one for someone who wants presence working in five min.

The SONOFF SNZB-06P Zigbee Human Presence Sensor (5.8GHz) earns a composite of 8.8, the budget entry point among the fully-local picks, because its normalized no-cloud factor scores 100% operating over ZHA or Zigbee2MQTT. For your particular configuration that delivers genuinely cloud-free presence affordably, with the occupancy timeout fully configurable inside Zigbee2MQTT. Tom's Guide observes that cluster-level timeout control is precisely the capability a closed vendor sensor deliberately withholds. Independent reviewers measured it triggering roughly 0.4 seconds behind the Apollo MSR-1 when entering from approximately 8 ft.

The sensor yields three distinct sensitivity tiers across its configurable detection distance, registering 88% on protocol openness. The Ambient characterizes the budget band as a sensible choice for mass deployment, but realistically only within smaller rooms. The honest limitation is false-trigger resistance, weighted deliberately at 18%, since the band predictably triggers from ceiling fans and household pets across its 13 ft reach.

Compared to the THIRDREALITY Smart Presence Sensor R3 (60GHz Zigbee), the SNZB-06P saves roughly 50% on purchase price, relinquishing breathing-level precision and a wider footprint to accomplish that economy across this roundup.

The Aqara Presence Sensor FP2 earns a composite of 7.9, the highest detection mark paired with the openness penalty the local-first buyer pays. For your HA setup it delivers the strongest zone gating here, scoring 92% on false-trigger resistance. The Verge highlights its 30-zone, 5-person tracking as best-in-class for suppressing out-of-zone movement across roughly 26 ft of coverage. A ceiling fan parked outside a defined zone produces no ghost trigger, which is why its false-trigger sub-score leads the field.

The catch is the path to HA, and the no-cloud factor scores it honestly. CNET notes the FP2 runs local through HomeKit Controller once paired, but first-run zone setup needs the Aqara app over 2.4GHz Wi-Fi. Its closed firmware yields no configurable clusters, so you cannot tune timeout or sensitivity the way an open Zigbee sensor permits.

Compared to the THIRDREALITY Smart Presence Sensor R3 (60GHz Zigbee), the FP2 detects and gates better. It does so on a Wi-Fi and HomeKit-Controller route rather than the R3's open native-Zigbee path.

The Aqara Presence Sensor FP300 earns a composite of 7.8, the field's only credible battery pick. For your configuration it delivers wireless presence where no power reaches. The Ambient documents up to 3-yr battery life on Zigbee. That drops to 2-yr operation on Thread. The dual-mode radar reaches roughly 20 ft. It is a 5-in-1 sensor reporting illumination, temperature, and humidity.

The tradeoff is protocol openness. The Verge notes the FP300 reaches HA through a vendor hub or a Thread border router. Its closed firmware yields no configurable clusters. The shipped Infrared-Radar combination trades a little responsiveness for the multi-year battery longevity. Its false-trigger resistance stays strong at 85%, helped by the 60GHz precision.

Compared to the SONOFF SNZB-06P24 Zigbee Presence Sensor (24GHz), the FP300 eliminates wiring entirely. It relinquishes the SONOFF's direct-pair openness and cluster configuration in return for battery freedom across this roundup.

The Aqara Presence Sensor FP1E earns a composite of 7.6, a strong detector held back by the field's lowest openness at 62%. For your HA setup it delivers wired 60GHz still-presence across roughly 20 ft at a 120° field of view, with AI spatial learning that adapts to the room over time. The 60GHz band rejects fan and HVAC airflow well, which keeps its false-trigger sub-score competitive.

The constraint is the integration path, and the protocol factor scores it accordingly. The unit reaches HA only through an Aqara Zigbee hub or a Matter-over-bridge route, and it is not officially supported on Zigbee2MQTT. Its closed firmware yields no configurable clusters, so timeout and sensitivity tuning are off the table inside HA.

Compared to the Aqara Presence Sensor FP2, the FP1E gives up the FP2's 30-zone gating. It keeps the breathing-level still detection but stays hub-locked for Aqara owners only.

The Tuya Zigbee mmWave Human Presence Sensor earns a composite of 8.0, the cheapest path into local presence. For your HA setup it delivers mostly-local operation once converted. Its no-cloud factor scores high, since it runs in Zigbee2MQTT after a Tuya converter takes it off the Tuya hub. CNET notes Tuya radars are inexpensive but report nonstandard clusters that need community quirks to map cleanly.

The protocol factor scores lower, because the conversion step and quirky clusters add friction the SONOFF picks avoid. The radar is airflow sensitive until you dial in the detection settings, which keeps its false-trigger sub-score modest. Once configured it yields adjustable detection settings inside HA.

Compared to the SONOFF SNZB-06P Zigbee Human Presence Sensor (5.8GHz), the Tuya unit is cheaper still. It trades the SONOFF's clean native Zigbee clusters for a converter step and quirkier reporting.
